AAA automotive researchers found that over the course of 4,000 miles of real-world driving, vehicles equipped with active driving assistance systems experienced some type of issue every 8 miles, on average. Researchers noted instances of trouble with the systems keeping the vehicles tested in their lane and coming too close to other vehicles or guardrails.

AAA testing showed that many advanced driver assistance systems experience issues that could cause crashes if relied upon by the driver. In the photo above, a 2019 BMW X7 with “Active Driving Assistant Professional” failed to identify and avoid a simulated disabled vehicle.
